COLLAPSIBLE CARTON.

To all whom it may cone-arm Be it known that I, JosnPH W. Wnrss, a citizen of the United States, and a resident of Baltimore, in the State of Maryland, have invented certain new and useful'Improvements in Collapsible Cartons, which the following is a speclficat on.

This invention relates to collapsible car tons and has special reference to means for reinforcing the same to increase their resistance to wear and mutilation due to rough handling during shipment and other conditions of use of cartons of this character.

In my co-pending application, Serial Number 726,003, I have disclosed a carton having the end edges thereof re1nforced by strengthening folds formedof the body of the material and provided with corner pleces within the folds.

The object of the present lnvention 1s to provide a strengthening corner piece which may be permanently attached to the exterior of the carton and which opens up and is collapsed together with the body of the carton.

With this in view I have provided an 1mproved construction the novel features of which will be fully set forth in the detalled description and particularly pointed out in the appended claims.

In the accompanying drawing 1llustrat ing this invention, Figure 1 is a perspective view illustrating a carton with my improved strengthening corner pieces attached thereto. Fig. 2 is a fragmental detall perspectlve View illustrating the corner piece partly cut avvav for the purpose of showing the meetin edges of the folds which it covers and rei nforces. Fig. 3 is a detail view illustrating the corner piece fiat previous to being attached to the carton. F1g. 4 1s a perspective view of the corner piece partly folded in the general posltlon it assumes when the box is set up.

The carton consists essentially of the vertical walls 1 and 2 and the end flaps 3, 4, 5 and 6. The material at the junction, of the walls and flaps is folded over to form strengthening ridges 7 and 8 suitably attached to the walls as by staples 9. All of this construction is described in detail in my co-pending application above referred to.

I will now proceed to describe a novel form of strengthening corner piece and its novel attachment to the corners of the car ton whereby this corner piece may be 001- Specification of Letters Patent.

lapsed together with the rest of the box, but when set up it affords a stiff reinforce.

Referring particularly to Figs. 3 and 4, the corner iece is preferably stamped out of some sti tough material as fiber board, leather, stiff fabric or light sheet metal, and consists of two substantially rectangular side walls 10 and 11 and two preferably triangular meeting top flaps or wings 12 and 13. A. slit 14 divides the flaps 12 and 13 and allows the same to be bent over so as to overlap one another as indicated in Fig. 4. The side walls 10 and 11 are attached in any suitable manner as by riveting, stapling, pasting or sewing to the side walls 1 and 2 of the box onto the ridges-7 and 8, and the flaps 12 and 13 are also similarly attached to the flaps 3 and 4.

When the box is set up the side wallsl and 2 are bent relatively to each other so as to assume the proper angle, and the corner pieces bend correspondingly along the junc tion of their walls 10 and 11. The flap 3 is then turned over carrying with it flap 12 of the corner piece, and the flap 4 is folded over to flap 3 carrying with it the fla 13 of the corner piece. When thus assem bled the edge 15 of the corner piece flap abuts against the interior of the junction of the flap 4 and the side wall of the carton, and thus constitutes a bracing member resisting compression. The other corner pieces are similarly attached and assembled, likewise resist-ing compression and thus together strengthen the box as a whole and maintain itrigid. The bridging of the corner pieces over the meeting edges of the ridges 7 and 8 protects the raw ends of the latter and tends ,to reinforce the portion of the ends of the box which are weakest. Moreover, the disposition of the wear resisting material abou the cornerstends to protect the same from abrasion and cutting and thus further prolongs the life of the box.

If desired, the lines of bending of the corner pieces may be provided with perforations 16, particularly when the corner pieces are formed of sheet.'metal and thus the assembling of the box is, facilitated, inasmuch as the metal ieces will readily bend along the perforate lines. These perforations, however, do not materially detract from the strengthening and wear resisting qualities of the corner pieces.

The line of bonding between the side walls and the triangular flaps of the corner piece is preferably located slightly above the vertical edges of the side walls, thus leaving an inclined portion 17 for passing over the edges of the box and avoiding the location of the projecting corners 18 at these edges.

It will thus be seen that I have provided a. collapsible carton, in which both the ends and corners are strengthened with a simple inexpensive construction which is very easily and quickly set up and collapsed. The corner pieces are permanently attached to the side and flaps of the carton and still can be collapsed flat, and when the carton is set up they afford a stiff reinforce to main-- tain the shape of the carton aswell as to protect the corners from Wear and mutilation. a

I have illustrated my improved strengthening corner piece as applied to a collapsible box or carton having reinforcing folds such as disclosed and claimed in my prior application, Ser. No. 726,003. When used with such carton, the corner piece in addition to strengthening the corner also protects the raw meeting edges of the folds. However, it may be understood that this corner piece may be used with advantage in connection with an ordinary collapsible slotted carton, as it will be seen that in any case, it will stiffen the box against compression and will bear the brunt of the wear which occurs on the corners.

Having thus described my invention, I claim:
